From: Genome re-sequencing reveals the evolutionary history of peach fruit edibility
The emergence of fruit edibility in peach species. a TreeMix analysis of P. mira, P. davidiana, P. kansuensis, and P. persica, using P. dulcis as the outgroup. A significant gene flow from P. kansuensis to P. mira was observed when migration = 1. b Four-taxon ABBA/BABA test of introgression. The excess of shared derived alleles (indicated by D values and Z-scores) were observed between P. kansuensis and P. persica, and between P. mira and P. persica. c dXY values of the introgressed segments and genome background for introgression between P. mira and P. kansuensis and between P. mira and P. persica. Significantly lower dXY values were observed in introgressed segments compared to the genome background. Horizontal lines at the center of each box show median values. Bounds of each box show the quartiles. The upper whisker extends to last datum less than Q3 + 1.5*IQR, where IQR is the interquartile range (Q3 - Q1). The lower whisker extends to last datum larger than Q3 - 1.5*IQR. d Analyses of the predicted genes embedded in introgressed segments. The number and the proportion of putative genes related to fruit edibility within introgressed segments are given inside the parentheses of the Venn diagram. Functional categories containing significant enrichment of gene ontology (GO) terms were presented using pie charts. Significantly enriched (P-value < 0.05, Fisher’s exact test) terms related to fruit edibility were classified into categories (Supplementary Data 6) based on their relatedness in the ontology or on functional proximity
